4.2.7.3 Connection of a brake unit
l When connecting a brake unit (brake module with internal brake resistor or brake chopper
with external brake resistor) observe the corresponding Operating Instructions in all cases.
Stop!
l Design the circuit so that, if the temperature monitoring of the brake unit is activated,
– the controllers are inhibited (X5/28 = LOW).
– the mains is disconnected.
l Examples:
– Chapter 4.3, “Installation of a CE-typical drive system”.
( & 4-34)
– Fig. 4-9, “Decentralized supply for DC-bus connection of several drives”. ( & 4-18)
